Specification of Letters Patent.

Be .it known that I, CHARLES AUmana, a

`citizen of 'the United States, residing at- Lisbon, inthe county lofRansom and State of North Dakota, have invented-certain new and usefulImprovements in Change-Mak-V o, finger pieces corresponding tothefactors with entering into the computations.

The ob3ects of the invention are to sim- 'plify the mechanism for makingthe computations and at the same time increase both the accuracy and thecapacity of the machine. .Y l,

The invention consists primarily in a machine embodying a control deviceor selector having motions in. two intersecting planes, the motion inone plane being controlled and determined by a set of keys correspondingto one set'of factors, and the motion in the other plane beingcontrolled and determined bya set of keys corresponding t-o another setof factors, any of which may be used in the computation, there vbeingmeans whereby the :position of` the selector will determine the result,such, for instance, as the discharge or indication of the proper changeto be given where the purchase price is one factor and the amountdeposited the other factor inthe computation. 1 y y More specifically,the, invention may be said to consist in a machine embodying a selectorhaving a rotary movement about its axis and a bodily movementlongitudinally of its axis, the two movements being controlled anddetermined by diderent sets tofkeys, whereby the selector may bepositioned.` any portion of its surface 1n proper relation to thecooperating mechanism lthrough which the desired result is effected.

"The invention further consists in certain novel details of constructionand combinationsand arrangements of parts all as will .Fig 2 is anelevation vation; and Fig. p

.The machine embodies in its general c onstruction the frame 11 havingsuitable bear-` ings therein for horizontal and vertical shafts to:loepresently described, and while it may be providedwlth a-cover or casingfor t. i the working parts of the machine, such cover or casing has beenomitted from the drawings, thus leaving the mechanical parts exposed toview. v

v Journaled nin two parallel upwardly extending portions of the mainframe, is a horizontal shaft 12, upon which shaft there is mounted aselector cylinder 13, the connection between the cylinder and shaft be-`ing such that they rotate in unison, but the cylinder is free to slidelongitudine ly of kl he shaft, the connection, if desired, bev ing inthe form of anordinary spline or key workingv in a groove-or channel 1nthe shaft Fheselector cylinder vis provided lgaita face with a pluralityof perforations orl apertures vvhichv are so arranged that when broughtinto proper relation to cooperating parts they will control such parts1n performing the functions for which the ma- Y chine lis designed.-Mechanism for accomis of novel construction and is so controlledarranged, the d esire in its rotary and longitudinal movements that alarge proportion of its area may be utilized and the capacity' formaking varied'- computations greatly increased. )ne set of keys, forinst moe, w1ll control the angular positioning of the selector, whlleanother set ofk'eys .willy control 'its vposition longiv,tudinally ofits axis and by having said sets of keys correspond to the factorsentering into the computation, it will be readily understoodv that theselector may be positioned by the operation of any portion of itssurface to the desired position, and by havin the a rtures ro e lresulrtwill belefztbd For convenience in positioning the selectorangularly about its axis it is provided with a. series of bars oryrbs 15of progressively vvarying length and extending parallel with the axis.For cooperation with these barsor ofwhich when pressed inwardly lisadapted to arrest the-rotation of; the selector with the appropriate ribrestingion the actuated key.

Thelongitudinal movement-V of the selector is also determined by a set ofkeys 65, said keys being arranged fin proper order to arrest thelongitudinal movement of the points, thus as shown in said Fig. 5, themovementl of the selector cylinder 13 toward the left has been arrestedby the contact of the edge of the Acylinder with the key bar 65, and itwill be understood that the other keys and166 would correspondinglydetermine the position of direct control of yeo k positioning resulttojfbe effected.

The spring 16 exerts a constant tendency to rotate theselector toward the front of the machine, as shown by thearrows in sprinto slid the cylinderin its proper normal position and to return the sameto that normal position after having been actuated, the shaft 12 isprovided at one end with a pinion 19 meshing with a gear segment 2Ojournaled Figs. 2 and 3,y

while the retention of the outer end of the in the slot 17 leavesthe'cylinder free. e longitudinallyof its shaft. To hold on a shaft 21. Theshaft 21 is provided with an arm 22 having a pin 22a the segment 20 toreturn or til the shaft 21 is actuated. The shaft 21 at its opposite endis provided with a gear segment 23 with which meshes a pinion 24 rotatedby a crank handle 26. They rotation of the crankhandle in the-directionindicated by the arrows. in Figs. 2 and\3 will therefore cause the pin22to inove away from in front of the'v segment 20 and said segment 20will be left free to advance in accoperating with' hold the sameuncordance with'the rotary movementl of thev selector under the inuenoeof the spring 16 toa point where such rot-ary movement is arrested bythe uated key of the series is however free to continue its forwardserves to actuate other parts of the mech.- anism, as will be presentlydescribed.

The mechanism-for moving the selector longitudinally understood from aninspection of Fig.4 4, wherein it will be seen that-a4 carriage 33 ismounted to slide longitudinally on guide bars or Ways 32 on-the mainframe. Said carriage has arms 35 and 36 embracing the selector, the arms36 however being pivoted on the carriage and held in operative positionfor moving the selector'byf spring 37, the arrangement being such thatif the car- -riage 1s moved toward the right in Fig. 4:

and theA selector is arrested lby one of the key bars 65, the arm 36will yield, permittm the carriage to continue lts movement, whlle theselector remains at rest. For moving ythe carriage itis provided with astud or antifriction roller projection 34.working in a groove 30 in acam cylinder 29 mounted on a shaft 28.v The groove 30 in the cylinder 29is at theends made substantially circular or in a plane perpendicular'to the axis of the cylindenwhereby the cam cylinder 29,willmake"apartial orv almost complete rotatiomifnecessary, before the movey mentofthe l 'uring such time they selectorv may be pocar'rlagepfisinaugurated, and

' connection-` 23,as shown in said Fig. 2.

cont-act with the `actuated key of the group From the 'foregoingdescription, the op eration of 'setting the selector will be readilyunderstood, for instance, one of the keys of each of the groups 66 and65 are operated and the crank handle turned inthe directio-n indicatedby the arrow with the result that during ,the .initial movement of thecrank handle the selector is permitted to turn under `the influence ofits spring until arrested by the 'appropriate rib 15 coming `in G6.After the completion of this operation `the rotation of the cam cylinder29 causes the cam portion of its groove 30 to move the carriage 33together with the selecto-r longitudinally of the shaftl '12, until theselector is, arrestvedby .engagement with the inwardly projected end ofthe actuated key of the group 65. Inasmuch as in the longitudinalmovementofthe selector the rib 15 would move out of engagement with theactuated key ot vthe group 66, provision is made for retaining theselector in its proper angular position by causing one of the ribstoimmediately move into engagement with a longitudinal guidewayl when'the longitudinal movement of the selector is inaugurated. Thislongitudinally extending guideway is conveniently the upper Aedge of theplate ,18,v which, as shownin Fig. 2,- lies in position to pass under`lany' one of the ribs which may be in posit on at the time thelongitudinalmovement is ina gurated.. The guide thus lformedby the ed leof the plate 18. will prevent any further forward rotation of theselector under the influence of its spring, and while it might bearranged to permit the selector to return to normal position the returnmovement of these-lector takes placeonlv after it assumed its normallongitudinal position on the shaft and is out of engagement with theaforesaid guide formed by the plate 18.

A The keys (35 and 66 are preferably' formed by bars mounted to slide insuitable guides on the main `frame-and at their outer ends are providedwith finger pieces, 67. They are rusually spring pressed in an outwarddirection as by springs a, Fig. 2, and they are held inwardly in theiroperative position spring pressed latches which willcoperatewithprojections 69 on vthe keys Whenever the latter are pushedinwardly. For releasing thekeys and permitting 'the-m .4 to return tonormal position a trip 71 over.- lying the' latches 70 is provided. Saidtrip' is pivoted at #2mn the main frame and @basa -linkponnebtfion-73--extending down .to'an arm 74 on a bell crank lever pi'`tied pressure on the fingerpi'ece or key 77', 'it is obvious willdepress the inner end of the ,trip 71 vso astov release thecatches'70,"thus providing for' the -release ot'v any key which may/have beenincorrectly operated or for Y the manual release of the keys betore theselector is returned to its normal position. Forautomatically 'releasingthe keys dur ing the return of the selector to its normal position athird arm'78 is provided on the sha-'tt carrying arms744 and 76, whicharm 78 projects into position to coperate with a pawl 79 .pivoted onlthe gear segment 23 (Figs. 1 and 2), the relation of the parts being asshown by the dotted and 'full lines in Fig.- 2, Whereby'as thesegment-returns toward its normal position, the end of the pawl 79engaging the arm 78, depressesthej latter and then, owing to the'changeinthe angular? relationship of the parts, slips ofi 'offthe end of thearm 78 and the parts assume the position shownin full lines with thekeys released, and the catches 70 lagain move into position4 to retain avkey when actuated.

The mechanism controlled'hy the Selector and'throughwhich the resultsaimed at are attained, consists generally of a 'seriesof spring pressedpins mounted in a'carriage or carrier adapted tobe advanced atftheproper time iorl cooperating with the selector, the apertures in theselectorperniitting the `pins toy enter which are to control theactuation of the mechanism, While, if no apertures are in position forthe Vpins to enter, the mechanism will not be operated. By the use ofcomparatively few `pins it becomes possible to` control 4the operationof mechanism fo-r'discharging coins of varying amounts, and if deslredthere 1s an alternative arrangement to cont-rol the discharge of papermoney-'of equal value.

Asishown in the accompanying drawings the series of. spring pressedp1ns44 are mounted to `slide vertically in` a' vertically movablecarriage or carriery 43. Theicarriage or carrier 43 is mounted ontheupper end of a shaft 42 adapted to slide in a bearing 41 in the mainframe, said shaft at its lower end being provided with a yoke 102 whichpasses around beneath the shaft 21 in position to belengaged anddepressed by a cam 101 on said shaft. The cam 101 cornes into operationto depress the carrier 43 and pins 44 after the selector` has been positioned. The return movement ef the carrier, pins and parts connectedtherewith maybe effected by a spring, such. for instance, as indicated`at 103 in Figs. l1 and 3.

`control of the coin discharging mechanism.

, brace fractional'currency, as heretofore indicated. y f

The lmechanism for, discharging silver coins up to four dollars,consists essentially of a coin stack 59 in which the silver dollars arepiled and having at the bottom four superposeddischargers each adaptedto disf charge a single'coin, and, whenall'are actuated-to dishargevfour coins. The discharg- 'ing'slides are indicated in the ldrawings bythe numbers '50, 51,- 52 and 53, each provided at its outer end with alockvy pin 54normally held elevated and with its upper end seated in aixed'locking bar 49 by a spring 55 (see Fig. 5),v but adapted to bedepressed to enter "a groove 56 ,in` afreciprocatory 'driver or bar 56.Obviously when depressed, the upperends of the pins move outof thelocking bar 49 and into the driver 56, and the reciprocation of thelatter will actuate the ejectors or any one of. them, whose pin is inengagement with the bar to discharge one or more coinsas the case maybe. The control of the pi'is7`5'4 is effected from the arms 45, beforereferred td, through the medium of the rods 46, the lower ends of iwhichextend down 'into the locking .bar 49 in position to' coperate withanddepress the pins' 54, whereby the ins 54 will be moved out ofengagement wit the lookin g bar, and into engagement with thereciprocatory driver 56. During the reciprocation ofthe .bar 56, theupper ends of the pins 54. will slide on the under surface of thelocking bar 49, as will be readilyunderstood from aninspection of Figs.1, 2 andv 5.

The coin ejector slides A50, 51,152l and 53 arepreferably arranged soythat theupper slides will operate o r insure the operation of allof theejectors below it, thus the upper ejectors` are' 'provided with` pins 50Whichextend down to .en age the lower ejectors as shown in Fig. 5, wereby the actuation of the ejectorsO, 51 and 52 alone becomes impossiblewithout theactuation of v the ejector 53, although ejector 53 may beactuated' alone to discharge a sin le coin, and'52 and 53 may beactuated to discharge two coins, etc.

The barf56 slides ways 56El in the vmain' frame, see Fig. 4, and isreciprocated bv arms 57en'a shaft60. f The shaft 60 at one end carries acrank 'arm 61 which at its ex- L tremity is joined to a sliding shaft 62extending, backfalongside of the, main .fran-:e

time the other edge of the and havin struck by t e end 63 of the gearsegment 39,

just as thelatter is completing its forwardA movement and after it'haspositioned the selector longitudinally of the shaft. By

pushing the. rod yor frame 62 forwardly, the

a projection 62'L adapted to be` bar 56v is actuated to advance any coinejector which at that time may be in engagement therewith through themedium lof l its in 54. The return movement ofthe bar. 56 1s effected bythe spring 64 which at one end may beconnected with the bearing 64a j inwhich the' end of the rod, shaft or frame 62 takes its bearing, as shownin Fig. 2.

As before stated, the ejectors 50 to 53 are competent to eject coins upto the value of four dollars, and.y in order to permitv of the giving ofchange in amounts equal in value `to nine dollars, provision 1s madewhereby when' the proper pin of the series 44 is operated a five dollarbillwill be. discharged.

To accomplish this there isl arranged along one side of the` machine areceptacle 81 which is divided by partitions 82 into compartmentsadapted for the recept-ionv of paper currency, the currency oftheproperv de-y nominationsbeing folded and placed b etween superposedplates 84lin thecompartments of the receptacles. One of the compartmentsis adapted for the holding of five dollar bills which are folded andplaced between t-he -plates 84, and these plates', together with billswhich may be located between adjacent platesl are dischargedinsuccession through the medium of the arm .1 46 connected with the lastpin 44 and the rod 48 carried by the arm 46 which extends down intoosition to coperate withand .actuate paw 93. The pawl 93 has an inclinedface 93L with which the endof the rod 48' engages, whereby the pawl willbe moved inwardly so as to enter and engage with a notch in thelowermost plate 84. The plates are supported atone edge on vledges 86and at the outer edge by short pins 83. The edgesof the'platesarenotched at 85, the notches being in such position that upon any'platebeing drawnv forwardly it. will bring the notchesrtherein into positionto register with the pins 83 and at the same plate will be moved off`of' the ledge 86 with the result that the plate is free to drop, and ofcourse Iwill permit the currencysupported thereby to drop or be ejectedfrom the machine. The pawl '93 is mounted on a reciprocatory carrier 94,preferably receiving its m'otionv from the reciprocatory bar v56. Asshown in the diagrammatic view, Fig. .5the carrier 94 is connecteddirectly with the bar 56 by a connection I5'6", but in the machine j aspreferably constructed and as shown in -the other views, the shaft60`carries at 'one' end a crank` armv "56a which is connected through alink 5T with thecarricr 94 whereby when the shaft 60 and reciprocatory.bar

56 are moved, the carrier will be correspondin ly moved, and, if at thattime the pawl l 93 has been moved into engagement with the 'bottom plate84 in the receptacle,as by the depression of the pin 44 and :ii-m46,said bottom plate will be moved in a direction to effect its releasefrom the receptacle and the discharge of both the pla-te'and the-ci'irrency held thereby.

y In some instances itis desirable to pro? vide for the payment ofchange either' in coin o1' in paper currency, and this may bevaccon'iplished by providin l a series of cur rency compartments 'in t ereceptacle 81,

i such currency compartments being adapted to contain bills, which willbe discharged by the operation of the selector controlled pins which asheretofore described Will e-Eectthe discharge of coins of like value, itbeing understood ofl course tthat provision lis made for checking the`discharge ofcoins when it is desired to make change in paper currency.`For operating the currency holding and discharging mechanism, the billsof proper denomination are folded between plates 84,

'such as before described, and the carrier 94 vis provided with 'pawls93, correspond1ng to the pawl 93 before described. `Each of the pawls 93is provided With-an inclined face `92, and with each there is adapted tocooperate a spring pressed pin v91 mounted in bearings on the side ofthe receptacle 81 and `adapted when depressed tomove the paivls int-oengagement With the'plates. vAbove the spring pressed pins 91 there isarranged a series of dogs 88, one dog foreach pin and all of the dogsare mounted ona carrier 87 movable longitudinally of the receptacle andadapted when in one position to bring the dogs into proper position fordepressing the -pins 91 Whenever the branches 90 of the rods 47- aredepressed. Conveniently, the dogs 88 are provided with heads 89 whichare moved .beneath the arms 90 by the longitudinal movement of the dogcarrier 87, said dogs thus acting as interponents between the arms 90and the pins 91. i The dog carrier 87 may' bemovedby hand, and heldinposit-ion by a locking pin 9S, Fig. ,5, and its movement maysimultaneously closeya door 97 for the discharge opening in the bottomplate 53 of l the coin stack 59, such simultaneous closure of the door97 being effected through suit-` able connections indicated atv 95, 96,in. Fig. 5.` In the preferredconstruction, the door 97 ,for closingthe-co1n discharge opening and prevent-in the ejection of coins iscontrolled y a han le,V 99, Figs. 1 and 3 which ,when

swung from the position shown in full lines to thatshown in dotted linesin Fig. 3, will close the coin discharge and by engagement vvith. the in99"(` on t e dog carrier 87 will move the atter into position forthedogs to operate in the manner heretofore described.

The handle 99 Will be retained in its position for preventing liedischarge of coins and holding the parts ready for the discharge of ingadapted to discharge or cooperate with the two vbottom pla-tes, and theother with a single bottom plate. The paWlcoper-'ating with the twobottom plates is actuated by an arm of the rod 47 which controlsthe'discharge of four coins and Will etl'ect the discharge of four dollarsin currency of four dollars in coin as the case may be. The

pawl cont-rolling the bottom plate of the two dollar bill compartment isitself'l controlled by the arm 90 of the rod 47 which coperates with thecoin ejector 52,- and consequently when actuated will discharge twodollars, as will be readilyr understood.V With this arrangement one,two, three orv'four dollars in either bills or coin may'bevdischargedlat the option of the person using the machine.

` The operation of the machine may be briefly described as follows.representing the value of a purchase is pressed inwardly' until latcliedand held in its operated position. 'A key 66, representing the amountreceived from the customer' and which of course is more than the valueof the purchase is also pressed in until A key 65 caught and held in itsoperated position. y

The handle 26 is now rotated the direction indicated by the arrowinFigs. 2 and 3 whereby the shaft 21 is rotated through the medium of the-pinion 24 and segment The arm 22 moves away from `tlv-f regu-ier.. 20or allows the segment 20 to advance as the selector is rotated under-teI influence of its im elling/ spring until the selector is arrested ythe operated key 66. "the continued rotation of thev shaft ai, ltogetherrwith the se ment 39 .meshing with the pinion 40 on t e shaft 28, causesthe cam' cylinder to rotate and advance the carrie 33 and selectorlongitudinally of the sha t 12 or until srch movement of the selector isarrested by the operated key of thagroup 65.l The selector isnow.positioned reis.,1 the proper apertures in position for`Acontrolling the mecianism for egectmg the 'pro er amount of change. Thecontinued rotation of the "shaft 91 brings the cani arm 101 intoengagement with the yoke 102, whereby the yoke, shaft to which it issecured'anv .The ,Proper carrier 43 will be depressed` llo i pinsfinding'apertures' to receive them in the selector, will continue tomove downwardly vwith `the pin carrier 43, while .the movement of theother pins will be arrested. Those pins 44 which continue to movedownwardly carry withthem the arms 45 or 46,

. and by so doing the handle 99 will havev together with the rods 48 andthe arms 90 on the rods 47. The actuated rods 47 will,

-through the pins' 54, cause the engagementv case it is not desired todischarge coins, the

doorl 97 will have been previously closed moved the dog carrier intoposition for the dogs l88v to form interponents between the arms 90 andthe ins 91, whereby paper currency will be dlscharged instead of coin.

. As soon as the discharge of either the paper currency or coin iseffected, the parts are returned to their normal positions -by arevers'erotation of the handle 26 .and during such reverse rotation the pawl 79will co operate with the arm 78 to release the o erated keys .andrestore them to their normal position. -As the carriage 33 returns toits normal position shownin Fig. 4, the spring pressed arm 36 will beinvariably returned to its normal-position by striking a projec-v Iclaim as new and tion' 4or shoulder 38 on 4the frame, but it will beunderstood that this spring-pressed arm 36 is but one of manyforms of:looseA connection which may -be interposed'v be-y tween the carriage andthe selector whereby the carriage may be permitted to make a -fullstroke while the selector is arrested at an intermediate point. v Havingthus described my invention what ing a cylindrical surface and movableboth angularly and axially, of two corresponding separate sets of keyseach set comprising a plurality of independent keys with means wherebythe keys of one set determine the angular movement, and the keys oftheother set determine the axial n'iovementofy i the selector.
